Sinusoidal PWM is a typical PWM technique. Nyob rau hauv cov txheej txheem PWM no, qhov sinusoidal AC voltage siv v r e f yog piv nrog lub high-frequency triangular carrier yoj nyob rau hauv lub sij hawm los txiav txim hloov lub xeev rau txhua tus ncej nyob rau hauv lub inverter.
Dab tsi yog sinusoidal PWM technique?
Sinusoidal PWM is a hom "carrier-based" pulse width modulation Carrier based PWM siv pre-defined modulation signals los txiav txim cov zis voltages. Nyob rau hauv sinusoidal PWM, lub teeb liab modulation yog sinusoidal, nrog lub ncov ntawm lub modulating teeb liab ib txwm tsawg tshaj li lub ncov ntawm lub carrier teeb liab.
Sine PWM inverter yog dab tsi?
Sinusoidal pulse width modulation yog txoj kev ntawmpulse width modulation siv hauv inverters. Lub inverter ua rau AC tso zis hluav taws xob los ntawm DC cov tswv yim los ntawm kev siv cov hloov hluav taws xob los simulate sine yoj los ntawm kev tsim ib lossis ntau square pulses ntawm voltage ib nrab voj voog.
PWM tswj qhov twg yog siv rau inverters?
Hysteresis maub los yog siv rau tam sim no qhov chaw inverter thiab tag nrho cov txheej txheem PWM tseem siv tau rau Voltage qhov inverter. Sinusoidal thiab Space Vector PWM cov txheej txheem feem ntau siv.
Tus neeg nqa khoom nthwv dej yog dab tsi thaum sinusoidal PWM?
Nyob rau hauv lub sinusoidal mem tes dav modulation, _ yog cov cab kuj yoj teeb liab. Nqe lus piav qhia: Hauv SPWM, ib lub voj voos peb-zaug ntau zausyog piv nrog qhov kev siv sinusoidal nthwv dej ntawm qhov xav tau ntau zaus. 6.
